Chemical Structure

1,1,1-Tris(hydroxymethyl)propane-d CAS 103782-76-9 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 1,1,1-Tris(hydroxymethyl)propane-d.

1,1,1-Tris(hydroxymethyl)propane-d (CAS 103782-76-9) is a high-purity analytical reference standard with the molecular formula C6H9D5O3 and a molecular weight of 139.20 g/mol.

Structurally, 1,1,1-Tris(hydroxymethyl)propane-d (C6H9D5O3) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 139.20 g/mol, it falls into the low-molecular-weight range.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
