Compared with other compounds in its class, the molecular weight of 265.18 g/mol gives 3-HO-TPHP distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-HO-TPHP (CAS 66003-88-1) is a high-purity analytical reference standard with the molecular formula C12H10O5P and a molecular weight of 265.18 g/mol.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-HO-TPHP is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-HO-TPHP 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.
