3,4,5-Trimethoxybenzaldehyde – 98%: name and identification
2 min
3,4,5-Trimethoxybenzaldehyde – 98%: an explanation of the name and catalogue data, with guidance on distinguishing variants and checking documentation.
How to read the name
“3,4,5-Trimethoxybenzaldehyde – 98%” is recorded in the OCA catalogue under number 86-81-7. Preserving the full name is important because the catalogue contains many similarly named aromatic derivatives. The initial notation 3,4,5 specifies the positions of the substituents named afterwards. Removing these numbers loses information about compound structure.
Reference record
| Information | OCA catalogue entry |

A distinction that matters
Retain additional identifiers alongside the common name. Different names for one compound should not create separate records for the same substance. This interprets nomenclature; it does not predict a particular sample’s melting point, solubility or reactivity.
One substance in several listings
A shared identifier links these names: 3,4,5-Trimethoxybenzaldehyde – 98%; 3,4,5-Trimethoxybenzaldehyde. Different purity claims remain properties of the individual offer variants. Do not choose the highest value and assign it to all listings.
What the catalogue establishes and what remains unconfirmed
For 3,4,5-Trimethoxybenzaldehyde – 98%, the listing is a starting point for identification, not a test certificate for the supplied batch. Read the purity result together with its method and batch number. A required water content, impurity profile or physical parameter needs its own specification entry. We do not add these values based on a similar isomer.
Similar notation, separate catalogue item
The formula C10H12O4 also appears in the “2,3,4-Trimethoxybenzaldehyde” listing. The molecular formula alone should therefore not be the sole search key. Compare full names and identifiers before merging documentation. A shared formula does not prove identical properties or product interchangeability.
