Chemical Structure

1,2-Dehydro Medroxyprogesterone CAS 3660-13-7 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 1,2-Dehydro Medroxyprogesterone.

1,2-Dehydro Medroxyprogesterone (CAS 3660-13-7), molecular formula C22H30O3 and molecular weight 342.47 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,2-Dehydro Medroxyprogesterone (C22H30O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 342.47 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
