Source-derived summary

1-Aminopropan-2-ol is the organic compound with the formula CH3CH(OH)CH2NH2. It is an amino alcohol. The term isopropanolamine may also refer more generally to the additional homologs diisopropanolamine (DIPA) and triisopropanolamine (TIPA).

1-Aminopropan-2-ol is chiral. It can be prepared by the addition of aqueous ammonia to propylene oxide.

Biosynthesis

(R)-1-Aminopropan-2-ol is one of the components incorporated in the biosynthesis of cobalamin. The O-phosphate ester is produced from threonine by the enzyme Threonine-phosphate decarboxylase.

Applications

The isopropanolamines are used as buffers. They are good solubilizers of oil and fat, so they are used to neutralize fatty acids and sulfonic acid-based surfactants.

Racemic 1-aminopropan-2-ol is typically used in metalworking fluid, waterborne coatings, personal care products, and in the production of titanium dioxide and polyurethanes.

Editorial summary

This brief starts where responsible research should: with the source description of “1-Aminopropan-2-ol” as pair of enantiomers. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 121-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where 1-Aminopropan-2-ol, pair and enantiomers can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as pair of enantiomers. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 10, 2026. The linked authority identifier is Q161580. None of the 0 selected statements returned an explicit reference.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
