Chemical Structure

Ethephon CAS 16672-87-0 chemical structure

Description

As a certified reference material (CRM), Ethephon meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Ethephon (CAS 16672-87-0), molecular formula C2H6ClO3P and molecular weight 144.49 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethephon (C2H6ClO3P) contains a phosphonate group, a carboxylic acid group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 144.49 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
