Pomona College is a private liberal arts college in Claremont, California. It was founded in 1887 by a group of Congregationalists who wanted to recreate a "college of the New England type" in Southern California, in the 1920s, it became the founding member of the Claremont Colleges consortium. Pomona is a four-year undergraduate institution, enrolled 1,700 students representing all 50 U. S. states and 63 countries as of fall 2018. The college offers 48 majors and 600 courses, though students have access to nearly 2000 additional courses at the other Claremont Colleges; the college's 140-acre main campus is in a residential community near the foothills of the San Gabriel Mountains.

News & World Report, The Wall Street Journal/Times Higher Education, it has an endowment of $2.27 billion as of June 2018, giving it the seventh-highest endowment per student of any college or university in the U.

S. In 2018, Niche ranked Pomona as university in the country; the college is a top producer of Fulbright recipients of other fellowships. Pomona College was established as a coeducational institution on October 14, 1887, by a group of Congregationalists; the founders' goal was to create a college in the same mold as small New England institutions. The college was located in Pomona, California; the next year, the school moved at the site of an unfinished hotel. This building would become Sumner Hall, the current location of Office of Admissions; the name Pomona College remained after the relocation. The college’s first graduating class, in 1894, had ten members, its founders’ values led to the college’s belief in educational equity. Like other Congregationalist-founded colleges such as Harvard, Dartmouth and Bowdoin, Pomona received its own governing board, ensuring its independence; the board of trustees was composed of graduates of Williams, Dartmouth and Yale, among others, to help create "a college of the New England type."

Although Pomona's first Asian and black students enrolled in 1897 and 1900 Pomona remained all-white throughout its early years. Daily attendance at chapel was mandated until 1921, a strong athletic culture and fraternity system developed. During World War I, the college oriented itself towards the war effort. In the early 1920s, the college’s growth led its president, James A. Blaisdell, to call for "a group of institutions divided into small colleges—somewhat of an Oxford type—around a library and other utilities which they would use in common." This would allow Pomona to retain its small, liberal arts-focused teaching while gaining the resources of a larger university. On October 14, 1925, Pomona’s 38th anniversary, the Claremont Colleges were incorporated; this decade saw the construction of additional residential buildings on the campus north of 6th St. The college's enrollment declined during the Great Depression, it once again oriented itself towards wartime activities during World War II.

From 1946 to 1956, the college ran a joint athletics program with Claremont Men's College. In the 1960s, the college became a hotbed of activism on the Vietnam War. In 1969, a bomb exploded at Carnegie Hall. Pomona's ethnic diversity began to increase around this time. In 1970, Pomona's athletics program joined with Pitzer to create the Pomona-Pitzer Sagehens. Throughout the 1980s and 1990s, the college added a variety of new buildings and its endowment grew steadily. In 1991, the college converted the dormitory basements used by fraternities into lounges, hastening a lowering of the profile of Greek life on campus. By 1997, the consortium reached its present membership of five undergraduate and two graduate institutions. In the late 2000s, the college began placing more emphasis on sustainability, it began enrolling higher numbers of low-income and minority students, created additional support structures for those students on campus. On December 8, 2016, Pomona announced that G. Gabrielle Starr, the Dean of New York University's College of Arts & Science, had been appointed to succeed David W. Oxtoby as president of the college.

The alma mater caused controversy when it was discovered that the song was written to be sung as the ensemble finale to a student-produced blackface minstrel show performed on campus in 1909 or 1910. Due to this controversy, the song was not sung during the 2008 commencement ceremony to give the college time to consider the song's future at Pomona. On December 15, 2008, the college announced a decision to retain the song as the alma mater, but not to sing the song at either commencement or convocation. In 2010, Pomona's dining service workers began attempts to form an independent labor union. Although 90% of dining hall staff and 50% of Pomona students signed a petition supporting the movement the college would only support an NLRB-regulated secret ballot; this was followed by a rally of workers and students, a vigil calling for labor peace, a demonstration of over 300 students and community members. The following year, the college requested proof of work authorization from all of its employees, including faculty, students on work-study, senior administration, following a "specific

Copper cyanurate is an organic compound. It has few uses, is more encountered accidentally, rather than synthesised, it is found when the copper concentration in an outdoor swimming pool is too high, it reacts with cyanuric acid to produce copper cyanurate. This phenomenon is called'Purple Cyanurate', as it discolours the surfaces and the water of the pool to a purple shade. Copper cyanurate can be created by reacting cyanuric acid with copper oxide. CuO + 2C3H3N3O3 → C3HCuN3O3 + H2O. Joanneumite is a rare natural mineral found in bat guano with formula Cu22, an ammine. By heating copper compounds, such as the nitrate or carbonate with molten urea up to 190°C, they are converted to the lavender coloured joanneumite compound; this recrystallised from a hot strong ammonia solution. If instead a weak cold ammonia solution is used, the dark purple compound CuC3N3O3H•2NH3 is formed instead. A green coloured copper cyanurate containing no extra water or ammonia ligands exists: Cu32. Copper cyanurate has no known practical uses.

The only place it occurs is as an adverse effect of high levels of copper in swimming pools, is more seen as a nuisance
