UNSPSC 51171643: Methylcellulose

This classification denotes a laxative with the molecular formula C29H54O16, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier O0GN6F9B2Y, chemically known as (2R,3R,4S,5R,6S)-4,5-dimethoxy-2-(methoxymethyl)-3-[(2S,3R,4S,5R,6R)-3, 4,5-trimethoxy-6-(methoxymethyl)oxan-2-yl]oxy-6-[(2R,3R,4S,5R,6R)-4,5, 6-trimethoxy-2-(methoxymethyl)oxan-3-yl]oxyoxane but generally known as methylcellulose, which bears US NIH Compound Identifier 44263857.

UNSPSC 51171643 Methylcellulose, a Commodity code, nominally covers chemical compounds used in pharmaceutical and industrial applications. However, the recent state and local solicitation activity tagged under this code does not reflect methylcellulose procurement; instead, Collin County Community Supervision and Corrections Department posted an RFP for offender specimen collection and drug testing services in September 2026, a classification mismatch that suggests either a data error or a misalignment between the code assignment and the actual procurement category. The code shows little relevant recent activity aligned with its nominal scope of chemical products.

The single recent opportunity under this code—Collin County RFP 2026-327 for drug testing services, due July 23, 2026, with an estimated contract value of $600,000—does not represent methylcellulose sourcing and therefore does not provide a reliable signal of state and local purchasing patterns or geographic concentration for this Commodity code. No other recent opportunities appear in the record. Business development professionals evaluating methylcellulose as a product line for state and local procurement should seek opportunities tagged under chemistry, laboratory supplies, or pharmaceutical ingredient codes rather than rely on activity under this classification.
