What Is the Structural Formula?

A structural formula is a chemical composition formula that represents the arrangement and combination of atoms in a compound (or elemental) molecule with element symbols and dashes. Is a simple way to describe the molecular structure.

Difference between molecular formula and isomer

Generally speaking, the structure of organic compounds is generally simplified. Generally, the carbon-hydrogen bond is omitted, and sometimes the carbon-carbon single bond is omitted.

Determining the structure of a compound can be quite daunting and meaningful

Structural formula introduction

With the popularization of computers, the input of organic structures in modern chemistry and chemical industry has become a major problem. Existing keyboards and input methods cannot complete the entry of complex structures. Professionals in the computer mainly use professional software for computer input:

1. Chemical language orchestration software

The software is relatively simple. The structural components often used in chemistry are collected through a huge database. Users can click to complete the entry of the required structural formulas, molecular formulas, etc. At the same time, the written structural formulas can be easily imported into documents in common formats . Simple operation, widely used in the industry.

2. Chemistry gold medal

Using the macro function in Word to complete the input of simple molecular formulas, it is difficult to implement complex structural formulas.

3.ChemOffice

A chemical professional software launched by foreign countries, which can complete the input of various molecular formulas, structural formulas, etc., with complete functions.

4.ChemDraw Std 14 product introduction:

ChemDraw can use ChemDraw to accurately process and map organic materials, organometals, polymeric materials and biopolymers (including amino acids, peptides, DNA and RNA sequences, etc.), as well as advanced forms such as stereochemistry.

By using ChemDraw, chemists can identify compounds that may have the required properties in advance, and then carry out the actual synthesis, so as to save time and reduce costs.

ChemDraw can predict compound properties, spectral data, IUPAC nomenclature, and calculate reaction metrics, saving research time and improving data accuracy.

This powerful set of tools can handle substructure query types (such as variable attachment points, R groups, ring / chain sizes, atoms / bonds / ring types, and general atoms), whether compounds are in commercial, public, or internal databases. Either way of storage can achieve fast retrieval.

ChemDraw is the world's leading scientific drawing tool. It is not only easy to use, high output quality, but also combines powerful chemical intelligence technology, integrated ChemOffice suite and many third-party products, which is loved by thousands of users.

ChemDraw includes some optional components: STATISTICA Base for more detailed numerical analysis; MNova Lite for fast processing of NMR data; chemical scripting language ChemScrip for automating structure-related processes and linking with other applications.

ChemDraw provides a complete and easy-to-use drawing solution for chemists, including drawing chemical structures and reaction equations, and obtaining corresponding attribute data, system naming, and spectral data ^[1] .

Structural meaning

The use of computer software for chemical structure drawing is the basis of chemical subject informationization and information processing, including structure storage, retrieval, calculation and design. For chemistry education and teaching. The use of chemical structural formulas, especially three-dimensional structures, is not only more visual and intuitive, but also an effective means to help students establish the three-characteristic thinking of "macro-micro-symbol" ^[2] .
