Chemical Structure

Tetrahydro-2H-pyran-2-carbonyl chloride CAS 40053-81-4 chemical structure

Description

Tetrahydro-2H-pyran-2-carbonyl chloride (CAS 40053-81-4), molecular formula C6H9ClO2 and molecular weight 148.59 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Tetrahydro-2H-pyran-2-carbonyl chloride (C6H9ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 148.59 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.

As a certified reference material (CRM), Tetrahydro-2H-pyran-2-carbonyl chloride 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.
