Analytical Standards (Others)

Analytical Standards (Others) — covers a wide range of analytical reference compounds that are not included in other specific standard groups, from zone-refined materials with multiple passes to marker compounds for determining specific contents by chromatography or spectrophotometry. This category complements analytical method validation needs beyond mass spectrometry or NMR standards.

Standards in this category are used by analytical laboratories for various purposes, such as gas-liquid chromatography (GLC) calibration, determination of total polyphenol content by spectrophotometry, and as reference materials with defined melting point and purity from zone refining. Its scope is broad because it gathers reference compounds from many different test methods, rather than a single analytical technique.

Example products in this collection: TCI B0224 92-52-4 Biphenyl Zone Refined (number of passes:24), TCI D0689 75-83-2 2,2-Dimethylbutane, TCI P3373 2754428-18-5 2-[(4-Methylpentan-2-yl)amino]-5-(phenylamino)cyclohexa-2,5-diene-1,4-dione, TCI E0854 831-61-8 Ethyl Gallate [for Determination of Total Polyphenol Content], TCI P0785 62240-27-1 Bis(2,2,2-trifluoroethyl) Phthalate [Standard for Phthalate GLC Determination].

Selection should consider the intended analytical method—whether for GLC, polyphenol testing, or melting point reference—as well as the purity level and purification history, such as the number of zone refining passes, which is listed for each compound. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
