3,3,3-Triphenylpropionic acid 2-triphenylmethylacetic acid 3,3 3-triphenyl propionic acid 3,3,3-triphenyl propanoic acid 2-triphenyl methyl acetic acid 3,3,3-triphenyl propionic acid 2-Tritylacetic acid 900-91-4 CAS 900-91-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,3,3-Triphenylpropionic acid 2-triphenylmethylacetic acid 3,3 3-triphenyl propionic acid 3,3,3-triphenyl propanoic acid 2-triphenyl methyl acetic acid 3,3,3-triphenyl propionic acid 2-Tritylacetic acid 900-91-4.

3,3,3-Triphenylpropionic acid 2-triphenylmethylacetic acid 3,3 3-triphenyl propionic acid 3,3,3-triphenyl propanoic acid 2-triphenyl methyl acetic acid 3,3,3-triphenyl propionic acid 2-Tritylacetic acid 900-91-4 (CAS 900-91-4) is a high-purity analytical reference standard with the molecular formula C21H36O2 and a molecular weight of 320.51 g/mol.

3,3,3-Triphenylpropionic acid 2-triphenylmethylacetic acid 3,3 3-triphenyl propionic acid 3,3,3-triphenyl propanoic acid 2-triphenyl methyl acetic acid 3,3,3-triphenyl propionic acid 2-Tritylacetic acid 900-91-4 (C21H36O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 3,3,3-Triphenylpropionic acid 2-triphenylmethylacetic acid 3,3 3-triphenyl propionic acid 3,3,3-triphenyl propanoic acid 2-triphenyl methyl acetic acid 3,3,3-triphenyl propionic acid 2-Tritylacetic acid 900-91-4 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
