Fine Chemical Materials Keyword Candidate Study

Filter-difference study

Against the 740-record Fine chemicals / Basic and process materials Supply-chain Study, this 735-record cohort shares 585 records. Only 150 occur here and 155 only in the reference; the union contains 890. These are filter-membership differences, not company entries or exits.

An ID-deduplicated archive snapshot, not the whole market, current recognition or operating results.

The largest recorded sub-industry participation gap is for Coatings and paints: 4/735 here versus 45/740 in the reference, an absolute difference of 5.5 percentage points. The cohorts have overlapping company IDs and are not independent samples.

Zero means no recorded label, not no business; multi-label cells overlap.

Multi-label counts can overlap; filter compliance is not industrial advantage.

Existing excerpts do not certify entire old reports; list linkage is not final recognition. Full definitions are on the series page.

Fields can overlap; hits establish search relevance only.

Intermediates and high-purity products need scale-up checks

The General-purpose fine chemicals label covers 199 records (27.1% of this cohort). This archive clue raises a verification question about Defined chemicals with process and pilot documents; it does not establish that these companies already deliver it.
